A flea weighs approximately 1 milligram and jumps at a speed of about 1.9 metres
per second.
Thus if 1 flea jumps from a surface per second, a force of approximately 1.9
micronewtons results.
If about 260,000 fleas jump per second, collectively they will provide about half a
newton of thrust
- comparable to the ion thrusters which NASA is currently
researching.
So, this spacecraft consists of a rear plate from which fleas are encouraged to jump
into the vacuum of space, propelling the craft on its journey.

Not as completely ludicrous as the title suggests.
But still quite so. |

Output = 260 killer flees |

According to fleascience.com an unfed flea weighs .45 mg. 260 000 fleas should weigh 117 grams. |

There seems to be no research whatsoever on whether a flea can survive in the vacuum of space. This is a serious oversight. |

I suppose this idea does present a risk that we may one day make it
to a habitable planet only to find that it's already thoroughly infested
by fleas that made it there years in advance. |

You're going to get a lot more reaction force from the same mass of LiDeT ... |
